Though his father and grandfather both played at TCU, Mayes opted to attend Minnesota out of high school. He started 15 games over his final two seasons, while playing all 26 games. He held an offer from TCU out of high school, but joined his brother at Minnesota.

Mayes opted to transfer to TCU in March. Had he not retired, he would have been required to sit out the 2017 season to retain his eligibility.

The decision appears to be fully voluntary, and not related to any health or disciplinary concerns.

Mayes’ full message:

“For those who have not heard yet, I have decided to stop playing football. I love the sport and everything it has done for me since I started playing in the 4th grade. I’ve built some amazing memories that will last for a lifetime. But the fire that I used to have for this sport just isn’t there anymore. I just want to thank everyone who has supported me throughout my playing career, it means the world to me and I love y’all. If you have anymore [sic] questions feel free to contact me.”
